IMPROVEMENT IN SPINNING-JACKS.

Be it known that we, JOSEPH H. Winrnmso'rron and JAMES LonD, bothofPhiladelphia, in the State of Penn. Sylvania, have invented a new anduseful Improvement in Spinning-Jacks; and we do hereby declare that thefollowing is a full'and exact description ot' the construction andoperation ot" the some, reference being had to the annexed dra-wings,forming part hereof, in which drawings- Figure 1 is a. perspective viewof a. portion of a spinning-jack showing the application of ourimprovement thereto.

Figure 2, an end elevation of the same.

Figure 3, a front elevation ofthe carriage end track, showing therace-pulley W.

The object of our improvement is to aid the spinner in winding the yarnon the bobbins, and to secure :t more regular twist in the yarn. Y 4 lTo enable others skilled in the art to make and use our improvement, wewill proceed to describe its construction and mode of operation. i

In the drawings, A represents the floor of a mill; B and Ortho-trackupon which the carriage D (that port of the jack bearing the spindles)moves to and from the rollerbeain. This roller-beam does not appear inthe drawings, but it forms a. wcll-known part of' the jackframe,`ol`which the beams E, F, and G constitute the rear side. H is e. shaft,with bearings :it J and K; it carries two pulleys L and M, of Awhich Lis a fast and M e, loose pulley, also a fast pulley N for the raee-belt,which gives motion to the carriages and spindles. O is the starting-bnr,which has a. free sliding motion, as shown. It is caused to press in thedirection o f the arrows by mechanism not shown. It carries the fork I,by which the belt, which transmits power from the main shaft of the millto the spinning-jack, is guided on und off the fast pulley L.

The parts thus for specified belong to spinning-jacks in general, andthey are here described only to enable us more easily topoirt out' theconstruction and mode of operation of ourimprovements. lhus:

We attach a. small wheel, R, `to the starting-bar `O by psssinga.Vsuitable stud through a. slot in this bar, as shown, There is e nut, a,by screwing or unscrcwing which this wheel R is heldin the desiredposition. S is an upright bnr, its upper end passing through a guide, asshown. It has attached to it rigidly, by set-screws or theirequivalents, a. projecting curved piece, T, which is intended to be keptin contact with wheel It. The lower end of the` bar S is joined by ahinge to the lever U, which is supported at its middle by the stand V'to which it is pivoted. X sind Y are two adjustable slides curved on oneside and grooved on the other. They are placed on the lever U, one oneach side of the .stand V, and fastened in place each by o. set-screw.rJhc slide X is intendedto be plcced at such a. point on the lever Uthat the race-pulley W shall come in contact with it at or nbout thetime the carriage is started inwards. The slide Y may be placed so thatthe race-pulley shall come in contact with it, and thus at such peint asthe spinner may desire to stop the inward motion of the carriage.

The operation of vour improvement is us follows: When the carriage D isout the spinner starts it in as usual, and the race-pulley Wet oncecomes in contact with theslideX, and thus deprcsses the outer ond of'the lever U, and correspondingly elcvates the inner end of the soniclever, forcing the projection 'l' against the wheel R, which moves thestarting-bar O, causing the fork I to guide the driving-belt partly onto the fest pulley L, and thus assist the spinner to turn thc spindlesand wind up the yarn. 'lhe carriage continuing its movement inwards therace-pulley W comes in contact with the slide Y, which depresses theinner end of the lever U, causing the fork I .to throw the driving-belton to the loose pulley hl, and thus stop the movement of the jack.

Having thus described our invention, we claim, and desire to secure hyLetters Patentl. The lever U, adjustable slides :ind Y, har S, curvedprojection T, nmlwhcel lt, in coinhiimtion with a spinning-jack, in themanner and for the purpose substantially as shown and described. 2. Thebar S, curved projection T, and wheel R, in combination with the.slnrtingdmr t.) ot n spinningjaok, substantially as described. 7 yJOSEPH H. WINTERBOT'IOM, i JAMES LORD.
